The error clearly say that a version system like coding is not correctly configured. Beside that please follow the issue template where it's kindly requested to put support questions on discourse.drone.io

I encounter this issue too.

When use drone from latest docker image, setting DRONE_CODING=true has no effect, result: "version control system not configured".

When build drone from git source code, It's works.

@eyeye do you have docker image that fixed this bug?

I found

git clone git@github.com:drone/drone-enterprise.git extras

go build -ldflags '-extldflags "-static" -X github.com/drone/drone/version.VersionDev=build.'${DRONE_BUILD_NUMBER} -o release/drone-server github.com/drone/drone/extras/cmd/drone-server

at .drone.sh,
You use drone-enterprise.git for extras to build the docker image, not the open source code.
Is that the problem?

@eyeye i found git clone git@github.com:drone/drone-enterprise.git extras at drone.sh

so release/drone-server build from git@github.com:drone/drone-enterprise.git/cmd/drone-server, i think drone-server in git@github.com:drone/drone-enterprise.git not supported coding.

@eyeye i tryed build drone from git source code , but it has other problem : sql: unknown driver \"sqlite3\" (forgotten import?), how you do that?

this is now fixed in drone/drone:latest
